Four 49ers who might lose their starting jobs soon

Consider, for a moment, that Chip Kelly, Jim Tomsula, Mike Nolan and Dennis Erickson all won their opening games as 49ers’ coaches. That should tell you that the 49ers shouldn’t put too much analysis into their opening-day drubbing to the Panthers. Nevertheless, the game could have provided a window into who might be losing their starting jobs in the next several games and the results could surprise you. Let’s go with the obvious first.

1. Zane Beadles. The embattled left guard gave up constant pressures, four to be exact and a sack according to Profootballfocus.com. Beadles also failed to maintain a block on a fourth-and-1, in which fullback Kyle Juszczyk lost a yard. Beadles could have picked up two more pressures, however, Hoyer got rid of the ball under two seconds, before Beadles’ man could provide pressure. The nightmare of an afternoon could mean former Lions guard Laken Tomilson could be promoted into the starting lineup as soon as this week.

2. Jacquiski Tarrt. The team’s free safety is an injury replacement for Jimmie Ward. Yet, coaches might hustle Ward back soon after Tarrt committed a silly personal foul by hitting a defenseless Greg Olsen in the Panthers’ loss. Tarrt also appeared to blow a coverage on a 40-yard catch-and-run for a touchdown by receiver Russell Shepard. Tarrt did some good things, like his one-handed interception and effective run support. However, coaches cannot yet rely on the second-year pro

3. Carlos Hyde. This might surprise some after Hyde rushed for 45 yards and on nine carries and caught the six passes thrown his way for 32 yards. However, Hyde only broke two tackles and only evaded two tacklers in his 15 opportunities with the ball. He also missed a pass protection and failed to make a man miss in space. His yards after contact was also meager. If Hyde fails to make more happen on his own he could see his carries diminish.

4. Brian Hoyer. The 49ers quarterback was near flawless in the first half with all 15 of his passes on target. His four incompletions in the half were due to two dropped passes, two good defensive plays. Nevertheless, 49ers pass protection is likely to be an issue throughout the season and Hoyer will need to move to open up opportunities. However, Hoyer has never been a movement in the pocket type of player. That’s why rookie C.J. Beathard could eventually get a chance.
